Understand How Your Credit Score Works

Your credit score gets mentioned like it's common knowledge, but nobody told you what it is or who's even looking. This explains it plainly: which UK agencies produce it, what feeds it, what damages it, and what you can do about it. For anyone who's heard the score matters and wants to stop it being a black box.
